Remaneicaris argentina ( Noodt, 1965)
( Figs. 1–2 View FIGURE 1 View FIGURE 2 )
Synonyms: Parastenocaris argentina ( Noodt 1965) ; Remaneicaris argentina ( Jakobi 1972) ; Parastenocaris argentina ( Rouch 1986) ; Parastenocaris argentina ( Dussart & Defaye 1990) ; Remaneicaris argentina ( Corgosinho & Martínez Arbizu 2005)
Material examined: Noodt's collection; C137 (M3, slide 11; locus typicus and M3, slide 12). Locus typicus: Rio Sierra (La Bolsa), in the mountain between the city of Córdoba and Alta Gracia (Carretera) , Córdoba Argentina .
Male: Length 450 µm (Noodt's measurement, from rostrum to distal rim of furca). Rostrum not fused to Cph, with wide base and two sensilla on tip. Cph and Urs2 with 1 dorsal integumental window each. Urs5 with 1 oval lateral window on each side of somite ( Noodt 1965). Anal operculum smooth and slightly concave. Furca as described by Noodt (1965); shorter than telson, 4 times longer than wide, in dorsal view constricted proximally and dilated at midlength, setae I–III and VII at the distal 1/3 opposite to each other, setae I–III approximately of same size, seta V the longest, seta IV longer than seta VI and VII, seta VI and VII approximately of same size. A1 and A2 armature and segmentation as described by Corgosinho eta al. (2007b) for R. tridactyla . A1: 9segmented, haplocer; armature beginning with proximal segment: 0/5/4/2/5+Ae/1/4/2/9+Ae. 2: with allobasis; 1segmented exp with 1 seta, 1segmented enp with 7 setae. Md, Mx1, Mx2 and Mxp armature as described by Corgosinho eta al. (2005, 2007a, 2007b and 2010a). Mx 2: of Remaneicaris type, with 2 slender setae on proximal endite and 3 setae on distal endite. P1 as described for female. P2 ( Fig. 1 View FIGURE 1 A): basis without outer seta, ornamented with 1 row of spinules on outer margin and 1 pore near anterior margin; exp 3segmented, exp1 longer than each of the remaining two segments; with PRVS on outer margin, row of spinules anterior to insertion of outer spine, 2 spinules of different size distal to outer spine and inner hyaline frill; exp2 without armature,with 1 spinule medially on outer margin and row of distal spinules of unequal sizes at distal margin; exp3 with 1 spinule located medially on outer margin, 1 row of spinules along outer corner, distal hyaline frill, 1 unipinate subapical spine and 2 bipinate apical setae, outer seta shorter than inner one; enp subcylindrical, 1segmented, nearly half the length of exp1, with 1 bare distal seta, two distal spinules and 2 spinules on outer margin. P3 ( Fig. 1 View FIGURE 1 B): basis with outer seta; enp 1segmented, pointed, with thin tip; exp 1segmented, straight, increasing distally, with proximal hump at 1/3 of inner margin, inner margin with small process on distal 2/3, 2 rows of spinules on outer margin, proximal row of 5 strong spinules, distal row of 4 spinules, distalmost with a hyaline lamella on inner margin,apophysis shorter than thumb, wider than long, with a well developed hyaline margin, which is inwardly turned at the end of a straight exp, conferring to it a final angle of approximately 90° with the main exp axis; thumb long, almost 2/3 as long as exp, inwardly curved on proximal third and almost straight on distal 2/3. P4 ( Fig. 1 View FIGURE 1 C): basis with outer seta and 1 pore on anterior margin; exp 3segmented, exp1 longer than each of the remaining two segments with PRVS on outer margin, row of spinules anterior to insertion of outer spine, 2 spinules of different sizes distal to outer spine and inner hyaline frill; exp2 without armature, with 1 spinule medially on outer margin and row of distal spinules of unequal sizes at distal margin (innermost spinules smaller than outermost ones); exp3 with 1 bipinate apical seta and 1 bipinate setae at 2/3 of outer margin, 1 distal hyaline frill and 2 spinules medially on outer margin; enp 1segmented, slightly longer than exp1, slender, with numerous spinules on inner margin. P5 ( Fig. 1 View FIGURE 1 D): without intercoxal sclerite, 2 plate not fused to the somite, trapezoidal, ending in small process on inner margin, with 1 long outer seta and 3 smooth distal setae, distal most the longest, proximal most the shortest.
Female: Sexually dimorphic in A1, P3, P4 and genital field.
Length 450 µm (Noodt's measurement). Rostrum as in male. Cph and double genital somite with 1 dorsal integumental window each. Urs4 with 1 oval lateral window on each side ( Fig. 2 View FIGURE 2 D). Furca ( Fig. 2 View FIGURE 2 D) as described by Noodt (1965), shorter than telson, 4 times longer than wide, in dorsal view constricted proximally and dilated at midlength, setae I–III and VII at the distal 1/3 opposite to each other, setae I–III approximately of same size, seta V the longest, seta IV longer than seta VI and VII, seta VI and VII approximately of same size. A1 armature and segmentation as described by Corgosinho eta al. (2007b) for R. tridactyla . A1: 7segmented; number of setae beginning at proximal segment: 0/4/5/2+Ae/1/2/9+Ae. A2 and P5: as in male. P1 ( Fig. 2 View FIGURE 2 A) basis with outer seta, 3 spinules on outer margin below outer seta; enp 2segmented, enp1 as long as exp1 and 2, without ornamentation on inner margin, outer margin with a strong spinule at the proximal 1/3 and 2 spinules at distal 2/3; enp2 with 4 spinules on inner margin and 2 on outer margin and 2 distal elements, 1 unipinate outer spine and 1geniculated seta twice as long as outer spine; exp 3segmented, exp1 with outer spine and rows of spinules on outer margin, exp2 unarmed, with spinules on outer margin, exp3 with spinules on outer margin, 1 unipinate outer spine on distal 2/3, 1 unipinate outer spine and 2 geniculated setae, innermost the longest. P3 ( Fig. 2 View FIGURE 2 B): basis with 1 outer seta; exp 2 segmented, exp1 with proximal row of spinules, outer spine, row of spinules proximal to outer spine and row of spinules distally, on inner margin; exp2 with 1 unipinate outer spine and 1 bipinate distal seta; enp 1segmented and spiniform, with 2 spinules at 3/4 of segment. P4 ( Fig. 2 View FIGURE 2 C): basis with row of spinules near enp insertion and 1 anterior pore; exp as in male, enp spinelike, as long as exp1, with 2 small spinules on inner margin and two larger spinules on outer margin. Genital field as described for R. analuizae ( Corgosinho & Martínez Arbizu, 2005) with 1 medially located copulatory pore. Gonopore is transverse slit.
